  Combretastatin A-4含硫杂环衍生物：合成，抗增殖活性和分子对接研究

  摘要：

  合成了Combretastatin A-4激发的杂环衍生物，并评估了其对微管蛋白聚合和细胞增殖的生物学活性。在上述19种含硫化合物中，衍生物（Z）-4h和（Z）-4j在纤维素微管蛋白聚合抑制和抗增殖活性方面表现出令人关注的效果，六个不同的细胞系介于8和27 nM之间具有IC 50值。此外，in silico在微管蛋白的秋水仙碱/ CA-4结合位点内进行了对接研究，以了解我们产品与蛋白质靶标的相互作用。还以1–10 nM的浓度研究了对滤泡性淋巴瘤细胞的细胞周期的影响，表明发生了凋亡过程。

  A series of isocombretastatins A has been synthesized by a new method based on the Negishi cross-coupling reaction in 19-84% yields. Five of the synthesized compounds exhibit high cytotoxic activity in nanomolar concentrations (IC50 = 1-100 nM) towards Jurkat, K562, Colo357, and A549 cell lines.

  Combretastatin A-4 and isocombretastatin A-4 derivatives having thiophenes or benzo[b]thiophenes instead of the B ring were prepared and evaluated for their in cellulo tubulin polymerization inhibition (TPI) and antiproliferative activities. The presence of the benzo[b]thiophene ring proved to have a crucial effect as most of the thiophene derivatives, except those having one methoxy group, were inactive to inhibit tubulin polymerization into microtubules. The influence of the attachment position was also studied: benzo[b]thiophenes having iso or cis 3,4,5-trimethoxystyrenes at position 2 were 12-30-fold more active than the 3-regioisomers for the TPI activity. Some of the novel designed compounds exhibited interesting anti-proliferative effects on two different cell lines. (C) 2015 Elsevier Ltd. All rights reserved.
